  • Patent number: 10684432
    Abstract: A fiber optic cable includes an optical fiber, strength components disposed on opposite sides of the optical fiber, and a polymeric cable jacket. The optical fiber includes a glass core, a glass cladding, and a polymer coating. The cable jacket surrounds the optical fiber and the strength components. Further, the cable jacket is tightly drawn onto the optical fiber, where excess fiber length of the optical fiber is such that positive strain is present in the optical fiber at room temperature (25° C.).

  • Patent number: 10684162
    Abstract: A vibration sensing optical fiber cable is provided. The cable includes at least one optical fiber embedded in the cable jacket such that vibrations from the environment are transmitted into the cable jacket to the optical fiber. The cable is configured in a variety of ways, including through spatial arrangement of the sensing fibers, through acoustic impedance matched materials, through internal vibration reflecting structures, and/or through acoustic lens features to enhance sensitivity of the cable for vibration detection/monitoring.

  • Publication number: 20200142144
    Abstract: An optical fiber cable includes a jacket and a plurality of stranded core subunits, each core subunit comprising a flexible sheath and a plurality of ribbons arranged in a ribbon group, wherein each ribbon of the plurality of ribbons comprises a plurality of connected fibers such that 50-70% of the cross-sectional area inside the sheath is occupied by the connected fibers. The flexible sheath may be an extruded PVC material that conforms to the shape of the ribbon stack and keeps all of the ribbons acting as a unitary body during bending.

  • Patent number: 10620393
    Abstract: A low attenuation optical cable is provided. The cable includes an outer cable jacket and at least one buffer tube surrounded by the cable jacket. The cable includes a plural number of optical fibers located within the channel of the at least one buffer tube. The cable includes small sized active particles located within the buffer tube, and an average maximum outer dimension of the active particles within the buffer tube is ?50 microns. The small sized active particles reduce microbending-based attenuation otherwise seen with larger sized active particles, particularly within densely packed buffer tubes.

    Abstract: A fiber optic ribbon cable includes a jacket of the cable, the jacket having a cavity defined therein, an optical element including an optical fiber and extending within the cavity of the jacket, and a dry water-blocking element extending along the optical element within the cavity. The dry water-blocking element is wrapped around the optical element with at least a portion of the dry water-blocking element disposed between another portion of the dry water-blocking element and the optical element, thereby defining an overlapping portion of the dry water-blocking element. The optical element interfaces with the overlapping portion to provide direct or indirect coupling between the optical element and the jacket.

  • Patent number: 10288827
    Abstract: A crush resistant optical cable and/or crush resistant optical fiber buffer tube are provided. The cable generally includes a tube having at least one layer formed from a first material and an optical fiber located within a channel of the first tube.
